The connecting rod bolt to withstands high tensile stress loads. Ultra light weight the lightest weight possible without compromising the conrod strength for high power use. The Tomei conrod thrust protector is designed to come into contact with the entire contact surface area rather that just the thrust aspect of the crank. When the connecting rod becomes one with the piston the connecting rods inertial weight and balance then plays a major factor in the smoothness of the engines rotation assembly and durability at high rpm.
The connecting rods role is to transfer the compressed pressure that the piston receives to the crankshaft. The forging process ensures that the conrod is capable of high stress loads at high PMS when the tension loads exceed 1 ton.
The conventional conrod is made as a whole piece and then it the main hole is cut into the body and later again cut into 2 pieces which weakens the conrod. Our original conrod was made as 2 separate pieces from the beginning.
Protecting the cranks thrust face if the thrust aspect of the connecting rods large end is designed as a simple circle, the conrod side will cause irregular wear on the cranks thrust aspect area and thus shortening the life of the crankshaft. Unlike other aftermarket conrod designs our beam conrod design does not have the oil feed in the of the rod from the big end. Sncm439 metal the sncm439 material is normally used only when considerably high rigidity is required. This bush experiences high load whilst providing oil hole from the top of the bar when the upper piston pin is pressed down when the conrod rises.
This way the is solid for maximum strength. Structure of the small end extra oil hole further increases lubrication efficiency. Small ends structure. Balance of inertial mass.
This minimizes the chances of elliptical deformations caused when under serious stress loads from serious power applications and thus maintaining the correct conrod bearings clearances. High strength conditions are key elements for the conrod for supporting a highly efficient turbocharged engine. 8 material sncm 439 conrod bolt size 3/8 24 height under neck mm 40 conrod bearing inner cecum 48 bearing wit hmm this design promotes strength while benefiting with weight reductions.
Development targets balance of strength and light weight. We chose to aim for overall strength while maintaining a light weight design. L19 is the top range type of APR rod bolts used since iota much higher strength material compared to the arp2000 and is capable of delivering the highest clamp loads possible.
Secured connection strength the strength of the connection is raised with the design aspects of the meting face of the rod. In order to guarantee overall strength where the rod is connected, the large end was made smoother and the shoulder form shaped was adopted. Nick pin to help prevent burns where the metal connects to one another a Nick sleeve is inserted in the bolthole to help reduce any gaps between the face of rod side and the cap side.
This method has proven to be the best for results in stronger connecting rods. The overall strength, balance and light weight properties that the Tomei connecting rod design will take your engine to the next level. Nickel was also added for extra tension resistance real strength when the rigidness is insufficient enough at the large end, the metal housing can deform, which can cause metal burns.
Please for more details. Tomei Nissan skyline RB26DETT RB25DE forged beam conrod kit spec conrod length mm a special thinner frame was designed with minimal burden on the threads. Not included with the semi custom order connecting rods. The conrod unique forging process the conrod body cap are forged separately the key factors in making the strength in the forged conrod lies in the metal flow or fiber flow.
Maintaining the rigidity of both the large end and small end. Reduction in the rod from buckling under high stress loads.
The threads was cut into the connecting rod side since no nuts are used which helps with weight reduction. APR molybdenum grease included the APR molybdenum grease is highly resistant against heat and pressure, enabling a accurate torque figure when tightening the fastener. The oil cap bush now has 2 holes for oil to enter for lubrication.
The weight factor itself will dramatically change the engines characteristics. Stronger, lighter, improved response designed for big race engines. The key points of metal flow fiber flow is to have the metal flow all in the same direction to maximise strength.
This maintains a more secured fitment.
